Hi.
I played with a ACSS shaft for a year. Also played with a 314 and 314/2 for years and also with the hp2. I switched back to the hp2. The acss has a lot of feedback and tons of spin. Playes supersweet. I switched back to the hp2 because I am simply more accurate with it. Nick vd berg playes with the ACSS for many years now and my junior teammate also played with it and he finished 3rd on the wc 9ball for juniors.
